Filed:

May 4, 2005

Appl. No.:

11/121857

Inventors:

Andrew J Ritz - Sammamish WA, US
John A Strange - San Isabel CO, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 11/00

US Classification:

714 48

Abstract:

A system and method for hardware error reporting and recovery is presented. An operating system provides an error signal handler, a platform-independent error processing module, and a platform-specific error handler. The error signal handler is configured to detect the occurrence of a hardware error and to notify the platform-independent error processing module of the detected hardware error. The platform-independent error processing module is configured to process the hardware error detected by the error signal handler. The platform-specific error handler is configured to perform platform-specific error processing of the hardware error in cooperation with the platform-independent error processing module.

International Classification:

G06F 11/00

US Classification:

714 48

Abstract:

A method and apparatus for correlating the identities of hardware devices, such as processors and memory controllers, between a local operating system and a global management entity is described. When the operating system detects a faulting device, the operating system generates a fault message and transmits the fault message to the global management entity. The global management entity determines the identity of the faulting device based on information contained in the fault message, selects an appropriate replacement device, changes a routing table to map to the replacement device to the identity of the faulting device, and transmits to the operating system a global identity of the replacement device. The operating system correlates the local identity of the replacement device with the global identity of the replacement device.

US Classification:

714 48

Abstract:

A method and apparatus for correlating the identities of hardware devices, such as processors or memory controllers, between a local operating system and a global management entity is described. In an embodiment a fault message including a local identifier of a faulting device is received from an operating system. A global identifier of the faulting device is determined that is different from the local identifier. An appropriate replacement device is then selected based on the global identifier of the faulting device, and the selected replacement device is mapped to the faulting device.

International Classification:

G06F 12/02

US Classification:

711165, 711E12002

Abstract:

A solid-state storage system is described with a method for adjusting the frequency of data retention operations. The data retention operation frequency can be increased or decreased according to a variety of environmental factors such as error code frequency, system temperature, altitude, and other operating conditions. These factors can indicate an increased or decreased risk of failure and accordingly provide increased or decreased rates of data retention operations.

Appl. No.:

Inventors:

- Woodinville WA, US

Assignee:

Transparent IO, Inc. - Woodinville WA

International Classification:

G06F 3/06

US Classification:

711162

Abstract:

A storage system may manage a logical unit using a differencing mechanism that captures changes to a base version of the logical unit. The logical unit may be presented to an operating system as a single storage device, while the logical unit may actually be provided by several storage devices that operate in conjunction with each other. In some cases, a single base version of the logical unit may be used to simultaneously provide multiple logical units, each of the logical units having a separate and independent differencing portion. In one such embodiment, a common base extent may contain read only versions of file blocks while each logical unit may contain independent differencing extents that contain changes to the base extent.

Assignee:

TRANSPARENT IO, INC. - Woodinville WA

International Classification:

G06F 17/30

US Classification:

707611

Abstract:

A storage system with a duplicate network storage device may change to and from a synchronous to asynchronous write connection based on a service level agreement. Degradation of a network connection or device performance may cause synchronous writes to be changed to asynchronous network writes, and synchronous writes may be performed on a second device. During the asynchronous operation, a differencing set may be created on a local storage device and used to update the network storage device. When the network storage device becomes able to meet the service level agreement with synchronous writes, the system may include the network storage device for synchronous writes.

International Classification:

G06F 15/177

US Classification:

709221, 709223

Abstract:

A remotely managed storage system may configure logical units using a low level storage controller on each managed computer system plus a target driver for each shared storage device. The storage controller may present logical units to operating systems running on a computer system and may operate on a lower level than a host operating system or hypervisor. A target driver may allow remote devices to use the local storage devices for other logical units. A storage master may configure the various components across a group of computers to create logical units of storage that are backed by multiple storage devices.
